You have to use DownG V36 (Mi3 compatible) for firmware.
And, after firmware, you have to flash a new BLE compatible ! (I recommand BLE 0.75 v10 for Mi3 from Cami)

For max speed with V5, you have to turn on the scooter with the brake pressed (hold the brake lever + power button)

For my mi 3, I use V6 with camiBLE 0.75 v10 and seem good, tested only a very short time !

Look at this, all is explain for mi 3 !!!

Thanks, it works now after BLE upgrade as you suggested.

But, with V5 firmware i can drive up to 29 km/h but not 35 km/h, do you know why this limit ?

Also, the scooter is no longer recognized by Xiaomi Home app , it always says : " scooter is not connected "
Is this normal ?

Speed on flat for me :
max 33/34km/h with 100%battery (70 kg)
with 50% battery...max 29/30km/h !

For Xiaomi Home app, I think it's normal...because you hack your scooter....lol !
But no need more Xiaomi Home app, you can do same thing with DownG or other app !

Tried V5 too.

I get the same error 42 but the scooter seems to work fine.

Looking forward to get a fix for this error by someone.

I test generating firmware in DRV223/DRV224, and I confirm that max speed is 30 km/h in this case...
I think the hack for 30 km/h limit don't work with scooter 3 !!! 😭

I have just tried flashing CamiAlfa BLE075_V10 using m365downg, but it ended up raising a 41 Error (scooter is not bricked, options can be changed using downG, but with a 41 error code).

But after that, I flashed the CFW V6 (v1.5.5) from https://mp365.es/hacktool/mi3/ (using DownG v36) and fixed the 41 Error Code in the same time! Looks like BLE075_V10 has some communication issues with the original firmware.

It's too cold out there to test right now, I'll keep you in touch in case of trouble.
